Patent JP-S61137423-A (JP)
Title: Digital input interface circuit
Inventor: FURUHATA MAKOTO
IPC: H01L27/08
Filed: 1984-12-10
Abstract: PURPOSE:To input a signal from a signal source to an IIL at a high speed with simple circuit constitution by connecting the base of a bipolar transistor (TR) to a constant current source, and connecting its emitter to the input signal source and its collector to the input side of the IIL. CONSTITUTION:When the signal source Sg goes up to a high level, the parasitic capacitance Cs at the input side of the IIL is charged speedily from a constant current circuit Ic1 through the P-N junction between the base and collector of the bipolar TRQ1, and the input side of the IIL becomes active immediately. When the signal source Sg goes down to a low level, a base current is supplied from the constant current circuit Ic1 to the bipolar TRQ1 immediately and a large collector current flows to the bipolar TRQ1, so that the input-side parasitic capacitance Cs of the IIL is discharged speedily. Consequently, the input side of the IIL is made inactive immediately.

Title: Method and device for evaluating gui and machine-readable recording medium recording program
Inventor: OKADA HIDEHIKO
IPC: G06F11/34
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To automate the evaluation of the consistency of graphical user interface(GUI) parts. SOLUTION: As to GUI parts such as a button, a parts group preparing means 101 compares an attribute value, e.g. vertical size, for every button and prepares a group of buttons, of which vertical size is equal. A hierarchical class preparing means 104 sets up a difference between the numbers of buttons included in respective groups as an inter-group distance and includes groups in the same cluster in the ascending order of distances to prepare a hierarchical cluster of groups. A cluster defining means 107 defines the sum of inter-group distances of groups included in the cluster as a cluster error, sets up the sum of errors of clusters included in the hierarchy as a hierarchical error and determines a cluster of hierarchy just before the hierarchy having a maximum error from the error of the preceding hierarchy as a cluster for error judgement.  An error group judging means 108 detects a cluster including a group having the maximum number of buttons from determined clusters and judges all groups included in the cluster as groups having correct vertical sizes and judges all groups included in remaining clusters as groups having vertical size errors.

Title: Direct positive color image forming method
Inventor: SHIBA KEISUKE
IPC: G03C1/485
Filed: 1986-10-31
Abstract: PURPOSE:To form a direct positive color image by a quick and simple processing to good finish quality by using a specific color developing soln. to process color development. CONSTITUTION:The color development is processed by using the color developing soln. having <=11.5 pH. More specifically, This developing soln. contains a restoring agent (excluding hydroxylamine) for the oxidant of an arom. primary amine color developing agent and a capturing agent for the oxidant of the restoring agent and contains preferably substantially no benzyl alcohol. One of the characteristics thereof lies in that the 'restoring agent' for restoring the oxidant of the color developing agent and the 'capturing agent' for capturing the oxidant of the restoring agent and returning the same to the original developing agent are made to co-exist. The color developing agent, the restoring agent and the capturing agent are defined by the mutual oxidation reduction properties necessary for forming the reaction system. The problems of defective desilvering are thereby decreased even if the quick processing is executed and the generation of suspended matter in a rinsing bath is obviated even if the processing is executed with the economized water.

Title: Detecting system for end of non-deciding program processing
Inventor: ITASHIKI AKIHIRO
IPC: G06F15/16
Filed: 1985-11-20
Abstract: PURPOSE:To detect the end of non-deciding program processing with no misjudgement by changing successively inferential processors to the busy states after the free state of each inferential processor is detected and then switching these processors to the free states when trials for all inferential processors are ended. CONSTITUTION:A management processor 2 detects that the inferential processors 1-1-1N of a multi-processor system are set in the free states respectively. Then the processor 2 confirms the free state for each of processors 1-1-1N and tries to switch these processor to the busy states. Then he busy state is changed again to the free state when the trial switching action is through with processors 11-1N. Thus it is judged that a non-deciding program is through. In such a way, it is avoided that the free state is judged mistakenly with the processor that starts its processing after the first free state is detected. This secures the detection of the end of the non-deciding program with no misjudgement.
